ISLAMABAD - Pakistan on Thursday said it was not warned about a U.S. missile strike in South Waziristan on Wednesday that killed six people and injured many others. Foreign Minister Shah Mahmood Qureshi while addressing a press conference here at the Foreign Office said, "Such attacks are "counter-productive" and could destabilize the situation." The attack on South Waziristan came in the wake of Chairman Joint Chiefs of Staff Committee Admiral Mike Mullen's visit to Pakistan and his assurances to Prime Minister Syed Yousuf Raza Gilani and Army Chief, General Ashfaq Pervez Kayani that his country would respect the sovereignty of Pakistan. Foreign Minister Qureshi said, "Such assurances combined with the missile strike indicated "an institutional disconnect" on the US side." He said it was agreed between the two countries that US would not violate Pakistan integrity. "Prime Minister Gilani in his meeting with Admiral Mullen had expressed Pakistan's point of view in clear terms and conveyed the aspirations of the people of Pakistan to him," Qureshi said. "Pakistan also conveyed to Admiral Mullen that there are principles to be observed at the international level and sovereignty of every country should be respected at all costs," he said. In the present circumstances, he said, there was a need to understand each other's point of view. He said, "My understanding of the rules of engagement is that no foreign troops will be permitted to operate in Pakistan." "If there is action required inside our territory, it will be carried out by our forces. Our stance is that we should cooperate with each other and such incursions cannot improve the atmosphere, rather they will deteriorate it and will be counter-productive," he added. However, he said, Pakistan too had a responsibility to ensure that there was no incident from its side of the border that violated the territory of others or impacted their sovereignty. He said there was a need of long- term strategy to address the situation adding that the internal realities and compulsions had to be kept in view. He castigated the political elements that were voicing opposition to the government on anti-terrorism policy adding that it was criticism for the sake of criticism. He said, "We have to protect our interests and protect our sovereignty and understand the given situation." Answering a query, he said the statement of Chief of Army Staff reflected Pakistan's policy in its true perspective. When asked about the ongoing Indo-Pak peace process, Foreign Minister Qureshi said that the peace process between the two countries was not halted. "Pakistan's delegation will visit India shortly to discuss the possibilities to increase trade across Line of Control in Kashmir," he said. Pakistan was keen to send its delegation to India to discuss bilateral issues including Kashmir, he said adding that the two countries needed to continue the peace process as it was in their best interest. He admitted that there were some difficulties but it was hoped that the meeting between President Asif Ali Zardari and Indian Prime Minister Dr Manmohan Singh on the sidelines of the UN General Assembly meeting in New York later this month would prove to be productive. Earlier, in his opening statement, Foreign Minister Qureshi said President Asif Ali Zardari would visit New York from September 22 to lead Pakistan's delegation at the annual meeting of the United Nations General Assembly. "During his five day tour, he will address the UN General Assembly besides holding important meetings on the sidelines with world leaders," he said. He said President Zardari was also expected to meet President Bush on the sidelines of UN General Assembly session to discuss the current situation on country's western border. "The President is also expected to have a meeting with Indian Prime Minister, Dr. Manmohan Singh, Afghan President Hamid Karzai and the UN Secretary General Ban Ki Moon," he said. He said the President would undertake his first official visit to China and dates for this visit were being worked out.
